On the Settings > Log Settings tab, there's a "Show tooltips" option. If that's enabled, it should show the line in a tooltip when you hover over it. However, if the line is too long, the tooltip will cause LogFusion to hang, so the tooltip gets truncated. You can adjust the max length in the Settings > Advanced Settings window.
I've also added your request for wrapping long lines to our list. If we're able to implement that in a future version, I'll be sure to post an update here
